Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a decorative concrete block for applying makeup to the front surface of a sheet pile used for revetment work and the like.

[Conventional technology]

If a sheet pile that has been driven into the ground for the purpose of revetment work is left as it is, it may tilt due to earth pressure, etc., so the head is usually reinforced with a reinforcement body called shade concrete. However, the part of the front surface of the sheet pile (on the seaside (water) side) that is normally below the cap concrete is exposed, and the monotonous surface is exposed, which seriously damages the landscape. In particular, when steel sheet piles are used, red rust is generated and the appearance is significantly impaired. In addition, dirt and stains have been generated over the years, and this will further damage the landscape. To prevent this, it is possible to apply makeup to the front of the sheet pile.
It is very troublesome to perform such work again on the sheet pile that has been once driven (in this respect, the same applies to the cased concrete).

[Problems to be solved by the device]

For example, in the case of applying makeup to a sheet pile, first, the water in front of the sheet pile is temporarily cut off to change the water, and then a scaffold is formed to assemble a formwork for placing concrete for makeup, and concrete is added to this. Hitting, then dismantling the formwork, scaffolding, and temporary deadline. In addition, even when forming shade concrete, stay materials called shorings are erected on the front and back surfaces of the sheet pile, a formwork is assembled on the stay material, and concrete is struck, and then these are dismantled. For this reason,
As can be seen in Japanese Patent Publication No. 089324, the front surface of the sheet pile is covered with a decorative plate, but its mounting was very complicated by tightening bolts one by one.

This invention is to solve such a problem,
The purpose is to embody a decorative concrete block for sheet pile that can be hung on the front of the sheet pile to cover up the sheet pile (apply makeup) and at the same time secure a space for driving the shade concrete.

[Means for Solving the Problems]

Under the above problems, the present invention is a decorative concrete block for a sheet pile that attaches a hanger to the back surface and hangs it on the front surface of the sheet pile with the hanger. It is formed on the thick lower backside through the horizontal backside step, and is hung on the sheet pile with a hanger so that the top surface of the upper backside is located between the top surface of the upper backside and the backside step portion, and at the rear of the sheet pile. The makeup of the sheet pile, which has a top surface higher than the top surface of the sheet pile, is erected, and the upper back surface, the back step and the frame provide space for driving concrete into the front, upper and back surfaces of the sheet pile. It provides concrete blocks for use.

[Action]

By taking the above means, first, if this decorative concrete block is hung on a sheet pile, the front face of the sheet pile is covered and the makeup is applied, and then the space near the top is surrounded by the sheet pile. By hitting concrete, it is possible to create shade concrete as it is.
Therefore, the cap concrete and the decorative block can be simultaneously applied to the sheet pile. Of course, after this, dismantling work is not required.

〔Example〕

 An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a perspective view of a makeup concrete block according to the present invention, and FIG. 2 is a cross-sectional view when a sheet pile is applied using this makeup concrete block. 1)
Has a shape in which an upper back surface 1b and a lower back surface 1c project in a stepwise manner with respect to a straight surface 1a by a back surface step portion 1d (the upper back surface 1b side is thin, and the lower back surface 1c side is thick).
Then, the surface 1a is applied with natural makeup as much as possible. As a makeup example, here is shown an uneven surface that looks like a natural stone is properly attached. Note that this unevenness can be easily formed by using an FRP form made from natural stone or a natural stone-like urethane form.

Next, usually prepare a plurality of metal hangers 3 of appropriate width to cover the top of the sheet pile 2 driven into the ground in a U shape, and fix the hangers 3 to the upper surface of the back step 1d with bolts 4 or the like. To do. An adjustment bolt 5 for adjusting the position of the sheet pile 2 is screwed on the upper surface and the back surface of the hanger 3. In addition to this, a sponge or similar material 6 is adhered to the lower surface of the lower back surface 1c to the full width, and a connecting metal fitting 7 for joining adjacent blocks 1 to both side surfaces of the upper back surface 1b.
Is provided.

Explaining the case of constructing the above block 1,
The block 1 is hung by a crane or the like on the sheet pile 2 buried in the ground and lowered. Then, the hanger 3 covers the top of the sheet pile 2. At this time, the adjustment bolts 5 and the like are adjusted so that the lower back surface 1c and the like are set parallel to the sheet pile 2. At this time, the height or the like of the hanger 2 is adjusted so that the top surface of the sheet pile 2 is located between the upper back surface 1b and the back surface step portion 1d. In addition, since it is necessary to match the height and the horizontal passage of the block 1 as much as possible, the above-mentioned material 6 is interposed at the joint surface between the lower back surface 1c and the sheet pile 2 to absorb the thickness change, and a wedge 8 or the like can be appropriately provided between them. And adjust. Of course, by adjusting the adjusting bolt 5, the height and the entrance / exit of the adjacent blocks 1 can be adjusted. If the position of the block 1 can be set in this way, fix it with bolts (not shown) to the connecting metal fitting 7, and if this is completed within an appropriate range, drive concrete between the upper back surface 1b and the sheet pile 2 (however, , A formwork 9 whose top surface is higher than the top surface of the sheet pile 2 is set up at an appropriate position behind the sheet pile 2). The concrete flows into the space 10 formed by the upper back surface 1b of the block 1, the back step 1d and the formwork 9, whereby the shade concrete 11 can be created, and also flows between the lower back surface 1c and the front of the sheet pile 2, The block 1 and the sheet pile 2 are integrated. Therefore, the space 10 formed by the block 1, the sheet pile 2 and the like also serves as a mold space for driving the shade concrete 11. At this time, the presence of the above-mentioned material 6 has an effect of preventing the concrete from leaking down when the concrete to be the shade concrete 11 is driven. Therefore, in this case, if the upper surface of the material 6 is set at a position higher than the water surface partitioned by the sheet pile 2, the concrete stops without touching the water (so-called underwater concrete does not exist), and the solid-dry property is excellent.

FIG. 3 is a side view showing another embodiment of the block 1. In this embodiment, the thickness is made thicker toward the lower part of the surface 1a, and by doing so, a solid and stable feeling is given. . FIG. 4 is also a plan view showing another embodiment, which is used for a steel sheet pile 2 (which may be made of concrete) which is meshed with each other in plan view and buried in an uneven shape. The surface of 1c is matched with the uneven shape of the sheet pile 2.

The above is the case of applying makeup or shade concrete to the sheet pile, but this block is also attached to the front of the existing sheet pile (the shade concrete has already been constructed) along with the anchor. Since it can be sewn with bolts, etc., this method should be used especially when it is desired to apply natural stone-like makeup to existing ones.

[Effect of device]

As described above, since the present invention has been described above, the following effects can be expected.

i) Since the front of the sheet pile is covered with variously decorated blocks, the monotonous surface of the sheet pile is not exposed and an accent is added to it to provide a great view. In particular, if you use a block with natural stone-like makeup, it matches the surrounding environment.

ii) If this block is hung on a sheet pile, it becomes a decorative material for the sheet pile, and at the same time, it also serves as a formwork for securing a space for driving concrete into the sheet pile to fix the block to the sheet pile.

iii) The construction of this block requires only bringing the block produced in the factory to the site, hooking it on the sheet pile, and driving in concrete, so the construction cost is lower than the conventional temporary deadline, formwork assembly, dismantling, etc. It is cheap and the construction period is short. At this time, the block can be attached and the shade concrete can be created at the same time, which can be expected to reduce costs.
